The term U-Boot actually simply means submarine.. Generally it is thought that the submarine was invented by Cornelius Drebbel in the 1500s, or by John Holland in the 1800s. The Walther U-Boot was invented by Helmut Walther. U-boat is the English translation of unterseaboot or under sea boat, shortened to U-boat.
